Allow
me to explain how sugar screws up this weight-regulatory system: that the sugar
fructose is much different than glucose and fats—contrary to a calorie is a
calorie. Too much sugar
is a poison—see
Prof Robert Lustig MD. We all need to know what has gone wrong so
that we know the fix, and not follow fad fixes such as exercise more and eat
less—the yo-yo diet. There is science that
proves where the harm lies and the fix to the weight-regulatory system. You
are not getting “a trust me, I’m an expert pitch”.
So bear with me while I will summarize (with links) the science.
First,
a little carb basics: Carbohydrates
(carbs) is the umbrella term for sugar molecules that have a 5 or 6
carbon-chain units. The most common unit is the 6-carbon glucose. Most glucose
is in chains called starches, of which for some we lack the enzymes to
break them upon into glucose; they are
fibers and cellulose. Other
common 6-carbon sugars are fructose
and galactose. There are several
important disaccharides (2 sugar units), dextrose, maltose, lactose, and
sucrose. Sucrose (table sugar) is
fructose and glucose. Sucrose is rapidly converted in the stomach
into single molecules for absorption in the intestines. High fructose corn syrup
(HFC 55) is 55%
fructose and 42% glucose, thus essentially the same as sucrose—both are equally
bad their fructose causes the havoc
(glycation) because fructose exists longer in an open-reactive chain
form.
You need not understand the process that caused
the medical conditions: just that there
is good science, that the fix has a science foundation, and that food
manufacturers oppose it. The havoc starts with a double assault on the liver by fructose. One arm of this assault is glycation, the random attachment of a simple sugar (monosaccharide)
to
a protein, which often hinders functions of that protein. Think of oxygen which
randomly attaches to
iron--a bad thing. “It appears that
fructose and galactose [from milk, not cheese] have over in vivo [in the body] ten times the glycation activity of glucose, the primary body fuel” Wiki. “Glycation is the first step in the evolution of these molecules
through a complex series of very slow reactions in the body known as Amadori reactions, Schiff base reactions, and Maillard reactions; which lead to advanced glycation end products (AGEs).
Some AGEs
[Advanced Glycation End products] are benign, but
others are more reactive than the sugars they are derived from, and are implicated
in many age-related chronic
diseases such as cardiovascular diseases (the
endothelium, fibrinogen, and collagen are damaged), Alzheimer's disease (amyloid
proteins are side-products of the reactions progressing to AGEs),[7][8] cancer (acrylamide
and other side-products are released), peripheral neuropathy (the myelin is
attacked), and other sensory losses such as deafness (due to demyelination). This range of
diseases is the result of the very basic level at which glycations [1]
interfere with molecular and cellular functioning throughout the body and [2]
the release of highly oxidizing side-products such as hydrogen peroxide” Wiki. Since 99% of
fructose is metabolized in the liver, it accumulates there. Thus, the liver is
subjected to the most damage of any organ by glycation.
The second hit comes
from fat accumulation in the liver. When
the liver is overloaded with glucose and
fructose from a meal high in starches and sugars, they are converted to
fats. However, only 20% of glucose goes
to the liver, compared to 99% of fructose, and glucose can be stored as
glycogen and doesn’t cause harm.
However, fructose can only be converted to glucose and thus glycogen, but
when there is no need, the liver converts fructose to fat (de
novo lipogenesis). Some fat is shipped
off in the blood; however, some-to-most, depending on conditions, is stored in
the liver. The combination of damage
from glycation to the liver cells (hepatocytes) and the excess fat in the liver
cause chronic inflammation of the liver and a problem called insulin resistance in the liver.
When
resistance to insulin occurs, more insulin is secreted by the pancreas and it
goes to the resistant tissues to promote absorption and metabolism of glucose,
to convert ADP to ATP, the energy molecule.
Insulin, to promote glucose metabolism, shuts down the metabolism of
fat, and causes fat to be stored. Thus,
insulin resistance causes increased fat storage. Insulin resistance in the liver
produces
gradually excess fat in the liver. This
is the second hit upon the liver. Too
much fat causes liver dysfunctions resulting in an inflamed liver and a medical
condition called non-alcoholic fatty
liver disease (NAFLD). The
extra 2 or 3 pounds of fat in the liver
slows liver conversion of glucose, thus higher blood insulin. Then extra insulin
is secreted to lower blood
glucose and this causes gradually insulin resistance in other tissues with its
gradually accumulation of fat.
Note: too much fat in the pancreas causes type-2 diabetes. As
just stated: insulin functions to cause the body to burn glucose and thus to stop burning fat and store it. All this starts with the double
whammy caused
by too much fructose: glycation and
fatty liver. The NHANES study in found in 1999 that over 30% of
adults have excess fat storage in the liver (NAFLD), a serious medical condition that can
progress to cirrhosis of the liver. Major
journal articles confirm
all of this. Prof Lustig MD calls sugar
(meaning
its fructose) a poison
comparable to alcohol, both cause a fatty liver and cirrhosis of
the liver.
It not the sugar
glucose, but fructose half, that is poison.
The Orientals on a traditional diet do not have a weight problem: their
diet is high in refined carbs (glucose);
many of them have over 70% of calories from white rice, yams, and noodles; but
only 15gm of sugar daily (vs our 124 gm).
On their traditional diet, they are among the healthiest people. Also
experiments comparing high fructose to
high glucose confirm the role of fructose alone. Nor is natural fats an issue[1]: Eskimos lack in their climate grains and
vegetables. Add sugar to their diet
along with traditional starches and they get the Western health issues. Unfortunately,
those with health issues
simply can’t fix the problem by avoiding sugar, no more that avoiding oxygen
fixes a rusty tool.
The fix is two-fold: to
end insulin resistance and turn off the weight regulatory system which
functions to restore the fat level and increase weight. A low-calorie diet will
not burn the liver fat
and thus lower the insulin level in response to glucose to its normal level and
keep it there, nor fix the weight regulatory system--avoid the yo-yo diet. One
reason is that for those who have kept
their weight on for a couple of years,
the system has reset to the new weight.
Hormones mainly secreted by the adipose (fat) tissue function to restore
their weight, even years later. Many
hormones are involved in this control; a major player is leptin, which is produce by the fat (adipose)
tissue. On an energy-restricted diet a
delayed-reaction occurs after 2 months, leptin will cause a 25% reduction in
metabolism, which makes the dieter tired and thus moody, bored, mentally
sluggish, and creates the feeling that to eat more will make that person feel
better. Even after the diet end, years
later, the leptin-system functions to restore the fat tissue to its former
level.[2] Nature
has supplied a way to end-run these systems.
It process is a bit complex, but the solution is simple.
When insulin is low as when sleeping (no glucose), the body
metabolizes fats for energy (ATP). Some
thought that by avoiding glucose (carbohydrates) during the day that insulin
would remain low and the dieter would stay in the fat burning mode. This is
the ketogenic diet popularized by Dr. Atkins.
A good idea shot down by a complex
system. Since proteins through hormones
incretins cause insulin
secretion, thus ketogenic
diet, like the calorie restricted diet, runs into the leptin energy reduction
at 2 months; thus the ketogenic diet faces the same obstacle that
simply
eating less has, they will not keep the dieter in the fat burning mode, and the
leptin system will cause the yo-yo diet for most on a ketogenic diet.
Now for the good news, when
we are sleeping the small store of
glucose & glycogen is burnt, than the body switches to metabolizing stored
fat. By not eating when getting up, fat
burning continues—this is the short-term fast.
Mammals have evolved a system that promotes survival during periods of food
shortage. That is why the reduction in
metabolism is delayed 2 months. But by
fasting, preferable alternate day fasting, the drop in metabolism doesn’t occur
at 2 months. And it gets better: to
promote hunting and gathering, when out of
glucose and protein from not eating, man burns fat with an increase in the
production of the energy molecule ATP of 10% above that under a normal diet—yes
more energy than normal. Secondly, the
energy and mood elevating catecholamine hormones dopamine, adrenalin and
noradrenalin are increased, and also the growth hormone HGH. Other than mild
hunger, the person without
food after awaking feels better than if he had a breakfast without
caffeine. And it get better, studies
show that by missing a meal or two, the daily calorie intake goes down, and
even more with alternate day fasting. The
scientific literature is clear on this fix. For
those who are obese or have type-2 diabetes alternate day fasting is best. In addition, to reduce insulin, replace carbs
with fats, and eat moderate protein (25-30 grams a day). For those who need
to just lose some pounds, simply
skip breakfast--link for advice
on fasting. Fasting eliminates the
excess fat in the liver to cure insulin resistance, the cause for obesity, and the
excess fat in the pancreas to cure type-2 diabetes. Bariatric
surgery cures type-2 diabetes because they fast following surgery, so too
does alternate day fasting—Dr.
Fung.
I have prepared a number of papers on what to eat, and
fasting. There are five recommended
diets depending on the health situation at Cleansing Diet and what to eat, and much more at its long version, and a guide at fasting is easy. There are many other benefits from a low
sugar diet since, as mentioned above the high fructose diet through glycation
and RAGE is the most significant causer for age related degenerative
diseases. If you want to know more, then
go to my website and use the internal Google Search Engine
to read the journal articles and my articles with links to them. You should
watch the documentaries and
lectures on YouTube. I have a video
page on my site which has links and a description of the best of
those
documentaries and lectures on diet, type-2 diabetes, CVD, bad pharma, and other issues related to
health. Drs. Lustig and Fung confirm my
presentation. For inspiration, I recommend reading the testimonial by Reyn’s wife on her very ill husband.
As recommended by Dr. Fung, Reyn did
alternate day fasting with a very low carb diet replaced with natural fats (not
vegetable oils), and from near death he regained his health.
Nothing is simple about our biological systems. Without understanding
the systems, we find
that all diet works for a while because people eat less, but they fail for
those with long-term weight problems, often years after they wrote a testimonial. Fasting
for most will produce long-term
results. It is easier than you think,
and it lowers the risk for the age related degenerative diseases, including cancer, and Alzheimer’s disease. Fat metabolism makes creates the
healthful beta
hydroxybutyrate. Low sugar and
high
fat (coconut oil is best) diet will undo the damage as new cells replace the
damage ones. Follow the science, please.

Trans fats and vegetable oils are not natural fats, both are made by food
manufacturers, and they damage the liver & more.

Obesity Code, and The Complete Guide
